Abstract
CASE: We describe the clinical and histopathological findings associated with a case of pyoderma gangrenosum (PG) after revision total hip arthroplasty. The patient developed an expanding purple-red, necrotic, ulcerative lesion at the surgical site, which was initially suspected to be either a surgical-site infection or warfarin-induced skin necrosis. After treatment with empiric intravenous antibiotics, surgical debridement, and vacuum-assisted closure of the wound, the patient had a painless hip with a remodeled scar and was asymptomatic at the seven-year follow-up. CONCLUSION: Confirmation of the diagnosis of surgical-site PG requires clinical-pathological correlation and familiarity with the PG skin lesion. Treatment of PG differs from treatment of infection; therefore, misdiagnosis and surgical treatment may exacerbate the clinical findings in PG.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
